This is to perform the packing operation by interposing the structure 20 and the joint 30 between the structure.

또한, 본 발명의 다른 실시예로는 이음부(30)의 누수방지를 위하여 이음부에 기 삽입되어 있는 이음부재(32)의 일부를 제거 후 수팽창패킹재몰드(70)을 삽입하고 여기에 이음부주입공(31)을 설치하며, 상기 이음부(30)의 공극에 배면주입을 위하여 구조물(20)의 배면까지 천공하여 주입 할 수 있는 배면주입공(21)을 천공형성하는 주입공 천공공정과,In addition, in another embodiment of the present invention to remove the portion of the joint member 32 is inserted into the joint to prevent the leakage of the joint portion 30 is inserted into the water-packing packing material mold 70 and An injection hole drilling process for installing a joint injection hole 31 and drilling a rear injection hole 21 that can be drilled and injected to the rear surface of the structure 20 for back injection into the cavity of the joint part 30. and,

이하, 본 발명의 작용에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

상기한 바와 같이 터널 또는 지하공동구, 지하철 등과 같은 구조물(20)의 신축이음부 및 시공이음부와 같은 이음부(30)의 누수를 방지할 수 있게 한 본 발명에 있어서 본 발명의 일 실시예와 같이 구조물(20)과 구조물(20) 사이의 이음부(30)에 수팽창패킹재(1)를 패드상으로 경화시킨 수팽창패킹패드를 개재시켜 패킹작업을 실시하면 평상시에도 우수한 패킹역할을 하지만 외부에서 수분침투시 상기 수팽창패킹패드의 초미립자시멘트와 우레탄수지가 수분을 흡수하며 팽창되므로 상기 수팽창패킹패드의 체적이 증가되어 구조물(20) 내부로의 누수가 방지되는 것이다.As described above, the present invention enables to prevent leakage of the joint portion 30 such as the expansion joint and the construction joint of the structure 20 such as a tunnel or an underground cavity, a subway, and the like. Likewise, when the packing operation is performed through the water-expandable packing pad, which hardened the water-expandable packing material 1 to the pad, on the joint portion 30 between the structure 20 and the structure 20, an excellent packing role is usually obtained. When water penetrates from the outside, the ultra fine cement and the urethane resin of the water-expandable packing pad are absorbed and expanded, thereby increasing the volume of the water-expanded packing pad, thereby preventing leakage into the structure 20.

또한, 본 발명의 다른 실시예와 같이 주입공 천공공정을 통하여 이음부(30)에 기 삽입되어 있는 이음부재(32)의 일부를 제거한 후 수팽창패킹재몰드(70)를 삽입하고, 여기에 이음부주입공(31)을 천공하며, 상기 이음부(30)의 양측에 배면주입을 위하여 구조물의 배면까지 천공되는 배면주입공(21)을 천공형성한 후 주입호스설치공정을 통하여 이음부주입공(31)과 배면주입공(21)에 각기 이음부주입호스(41)와 배면주입호스(42)를 설치하고 주입공정을 통하여 이음부주입호스(41)와 배면주입호스(42)를 통하여 수팽창패킹재(1)를 액상으로 주입하며, 상기 주입공정을 통하여 양생이 완료된 상태에서 마감처리공정을 통하여 이음부에 컴프레션실(50)(Compression Seal)을 삽입하고 상기 컴프레션실(50)이 삽입된 이음부(30)에 실런트(60)로 메움작업하여 패킹작업을 실시하므로서 평상시에도 우수한 패킹역할을 하지만 외부에서 수분침투시 상기 수팽창패킹재(1)의 초미립자시멘트와 우레탄수지가 수분을 흡수하며 팽창되므로 상기 수팽창패킹재의 체적이 증가되어 구조물 내부로의 누수가 효과적으로 방지되는 것이다.In addition, after removing a part of the joint member 32 that is previously inserted into the joint portion 30 through the injection hole drilling process as in another embodiment of the present invention, the water-packing packing material mold 70 is inserted therein, and Perforating the joint injection hole 31, and forming a perforated back injection hole 21 perforated to the back of the structure for back injection on both sides of the joint part 30, and then through the injection hose installation process 31) and the joint injection hose 41 and the rear injection hose 42 are respectively installed in the back injection hole 21 and the water expansion through the joint injection hose 41 and the rear injection hose 42 through the injection process. The packing material 1 is injected into the liquid phase, and in the state where curing is completed through the injection process, a compression seal 50 is inserted into the joint portion through the finishing process, and the compression chamber 50 is inserted. Packing work is performed by filling the joint 30 with a sealant 60. In general, it serves as an excellent packing, but when the water penetrates from the outside, the ultra-fine particle cement and urethane resin of the water-expandable packing material (1) expand and absorb water, thereby increasing the volume of the water-expandable packing material and effectively leaking water into the structure. To be prevented.

따라서, 본 발명은 터널 또는 지하 공동구, 지하철 등과 같은 구조물의 신축이음부와 시공이음부 등과 같은 이음부에 수팽창패킹재로 패킹 처리하여 누수를 방지하므로서 평상시에도 누수가 효과적으로 방지되지만 외부에서 수분이 다량 유입시 상기 수팽창패킹재가 팽창되어 수분침투를 차단하므로 누수 방지효과가 우수하고 매우 유용한 것이다.Therefore, the present invention effectively prevents leaks by packing water-expanded packing materials in expansion joints and construction joints of structures such as tunnels or underground joint holes, subways, etc. The water-expandable packing material is expanded when a large amount is introduced to block the water infiltration, so the leakage preventing effect is excellent and very useful.
